Specieaton of Letters Patent.

Application filed April 6,1906. Serial No. 310,251.

.To il whom, 71mg/ concern:

Be it known that l, ,latins B. TALBOT, a citizen ol the United States, residing in Ed- Wardsville, in the county of Madison and State of Illinois, have invented certain newY and useful Improvements in Apparatus for Molding Cement Blocks, of which the following is a full, clear, and exact description, rel ercnco being had to the accompanying draw ings, forming part of this speeicati on.

My invention relates to that type of cement block Inoldin apparatuses shown and de scribed in nited States Letters Patent granted to Thos. Fischer and myself November 1i, 1905, No. 804,528.

The objects of my proscrit improvement are to so construct a cement block molding apparatus that various shapes oi blocks inav be laid therein; also that blocks may be made in the apparatus; and also a construction whereby the separable mold niernhers may be readily and quicldi7 clamped in molding position and released after the molding operation has been coni-V pleted.

Figure I is a top or plan View of my apparatus. Fig. Il is a View partly in side elevation and partly in vertical longitudinal section. Fig. Ill is a front end elevation of the apparatus. Fig. IV is a vertical cross see'-Y tion taken on line IV`IV, Fig. I. Fig. Vis aV Vertical cross section taken on line V-V, Fig.

Fig. VI is an enlarged vertical section taken through the central portion of one of the side wall mold compartment sections and showing a detachable bead strip applied thereto through the medium of whichV the grooves in the ends of the incid blocks may be produced. Fig. VII is a similar View to Fig. Vl, the bead strip being omitted and its receiving pocket being shown closed by a filler strip. Fig. VIII is a perspective View of a series of blocks of the forni produced in my apparatus shown assembled in the positions they occup)T When laid in a mold.

A designates a carriage that is provided with a platform 1 and is supported Vby track Wheels 2 which are adapted to ride upon track rails B. The carriage A is adapted to carry the molding members to be hereinafter described.

3 designates a imposed above rails B, and 4 is sitioned between said outer rods.

pair of outer core rods superthe track consisting of the an intermediate core rod po- The rear different sizes of l ends oil thc rods 3 and 4 extend through an upright member 5 and are inclined downwardly at the rear of said member and ernliedded within a body of concrete, whereby heldironi inovernent. The forward free ends of the core rods 3 are provided with taperin f heads free end of the intermediate core rod is provided with a tapering head 4. These heads are shaped as mentioned in order that the transverse inold ineinbers to be hereinafter inntioned will more readily ride onto said ro s.

7 designates a series of transverse mold boards that are. provided With apertures corresponding ,in number to the outer and interi mediate core rods, and adapted to be threadi cd onto said core rods, the apertures in said mold board being of dimensions correspond ing' approximately to the dimensions of the coro rods onto which the r are fitted. Each of the transverse mold cards is provided near its outer edges and near the top with outer rod-receiving holes 8 and inner rod-receiring holes 9.

It) designates side mold compartment sections lthat separate the transverse mold i boards by being positioned between the al- Y ternating pairs thereof and which determine the Width of the cement blocks that are to lee'niolded in the a paratus. These mold sections 10 are pre erably of trough like shape havin flanges at their outer sides. The inside 'faces of the sections may be in l the form of plane surfaces in order that a Hat moldin face may be produced upon the ceinent block at thev portion Which is molded in contact With anyr particular section or the sections may have configurations at their inner faces whereby the molded blocks may be producedwith faces simulating rough stone.

11 designates the bottom mold members which are positioned bet-Ween pairs of the transverse moldY board and airs of the side l mold sections it). Each o these bottom l members is preferably formed with anges that rest upon the carriage platform 1 that jl supports the members 7 and 10, and the botthe rods are rigidly Vtoni members may be formed in a manner similar to that described with respect to the sido sections, in order that the blocks produced may be formed With either plane faces l or irregular faces. The rearmost transverse mold hoard is adapted to rest ainst upright strips 12 located i-n front of t e upright member 5 of the apparatus whereby said 3 and the forward ICO IlO

niold board is maintained in vertical position while the for-1 most transverse mold board is held at its lower edge by a clamp lever l that when moved into clampingl position serves to cause a bindiner action upon the foremost mold board that is transmitted therefrom through the various transverse mold boards and .side mold sections toward the rearmost mold board, to maintain all olsaid members in a closely assembled condition.

14 designates binding' rods that are adapted. to be passed through either the outer series of rod-receiving holes S in the transverse mold boards or the inner series El of rod-receiving holes according to the positions in which it may be desiled to hold the side mold section lt). Each binding rod is provided at one end with ahead and is threaded atits other end to receive a clamp nut l5. lt will be seen that when the bindingl rods are passed through either series of the bolt holes in the transverse mold boards and the clamp nuts are tightened on said rods, tlfc transverse mold boards and the side mold sections located between them are bound tightly togethel; at their upper portions. The binding rods 14 are adapted to be passed through the outer rod-receivingI holes 8 when the side mold sections 10 are to be maintained in upright positions to produce end faces on the blocks at richt angles to the tops of the blocks considered with reference to their position in the apparatus, and the rods are adapted to be passed through the inner holes 9 when it desired to hold the upper ends of the side mold sections inwardly to produce blocks having tapering end faces.

16 designates bindinr strips that are loosely seated on the carriage platform 1 and are adapted to bear against the lower ends of the side mold sections 10, as seen most clearly in Figs. HI to V inclusive. These binding.' strips extend longitudinally of the carriage platform and are of len Yths corresponding to or exceeding the combined series of mold members, whereby each binding strip serves to hold the lower ends of the entire set of side mold sections at the side of the multiple mold at which it is located. Thebindingr strips 14 are adapted to be held for binding action against the side mold sections by clamp levers 17 mounted upon the carriage platform 1.

10 designates bead strips u )on the inner faces of the side mold sections that are adapted by their presence thereon. to cause pro duction of grooves in the ends of the cement blocks similar to those shown and described in the Letters Patent hereinbefore mentioned, and of which no further description is deemed necessary. These bead strips may be rigidly secured to or formed integral with the side mold sections, but they are at least in part made detachable from said sections in order that where desirable, as in the instance ol' producing" bloehs having' end faces that are to be exposed at the exterior oll a wall. said strips may be removed, 'lhe bead strips may be detaehablv lifted 1o the side lnold sections by any suitable menus, such as screws lo" (see lfil" Vl, or the strips ma' be provided with dove-tnil tenons In to seat in correspondiugly shaped poeliets l'ornied in the side lnold sections lll, as seen in lfm'. \`l. there the latter l'orln oll construction is made use of the pocket that receives the tenon of each strip may be closed by a tiller strip r, as seen in Fic'. Vll, l'or the purpose ol' rendering the mold face of the mold section llush.

lfor the purpose of providing for the pro duction of cement blocks of smaller sizes than those produced in the main portion of the machine in which the mold com )artnients extend entirely across the multiple mold7 l subdivide the mold compartments by introdueiner into any desired number of them partitions 1N that are provided with sleeves l?) fitted to the intermediate core rod 4 and extending` longitudinally thereon. It will be seen that these partitions afford )roper moldingI faces for blocks to be molded at each side thereof, and that the sleeves have the same utility as the intermediate core rod in that they produce matchingr grooves in the molded blocks.
